summary	Expert systems are a novel software technology which aim to model the behavior and knowledge of human experts. This paper presents two modes of interaction between graphics and expert systems in the domain of computer-aided design. The first concerns the interaction between an expert system and commercial CAD systems. The second demonstrates how expert systems can control design oriented graphical representations. Examples from both modes are presented from systems developed at Sydney University

title	The Terminal Crit

summary	Numerous attempts have been made to develop formal design methods with -the purpose of increasing the predictability, consistency and dissemination of the design process and improving the quality of the objects produced. The ill- structured nature of design, and the perception of design activities as intuitive and experience dependent have frustrated many of the efforts to structure these process. The growing complexity of the built environment and advances in technology have led to a more rigorous effort to understand and externalize creative activities. Computer aided design tools have recently been playing an important role in the evolution of the design process as a rationally defined activity. The use of- computers for drafting, analysis, and 2 or 3 dimensional modeling is rapidly becoming an accepted method in many design schools and practitioners. A next logical step in the externalization of the design process is to endow the computer with the ability to manipulate and critique parts of the design. Under this scenario, the "terminal crit" is redefined to mean critiques that are carried out by both the designer and the computer. The paper presents the rationalization of the design process as a continuum into which CAD has been introduced. The effects of computers on the design process are studied through a specific incorporation of CAD tools into a conventional design studio, and a research project intended to advance the role of CAD in design.

summary	During the past few years we have been involved in a variety of experiments that teach the use of computers to non-computer oriented architecture students. These teaching experiences have led to the development of an experimental, entry-level course in computer-aided architectural design using the Macintosh personal computer. Objectives of this course included: a) to provide an introductory course to students with little or no prior computer experience, b) to use the course as a vehicle for illustrating principles of computer-aided design, c) to course so that it would be applicable to design in general, not just architectural design, and d) whenever possible, to use "off the shelf', generic, readily accessible software. The history of these developments will be presented along with a very preliminary evaluation of results.

title	Business objects in construct IT
source	R. Amor (ed.) Product and Process Modelling in the Building Industry, Building Research Establishment, Watford, England, pp. 117-130
summary	Objective: EU Esprit Project 25.741 Wonda aims to meet the needs for Enterprise Information Systems and E-Commerce in the construction and banking industries. Wonda aims to deliver a solution suitable for contracting firms. The solution should enable take-up by SMEs, incremental value-added growth (perhaps Incremental Radicalism), mobile computing for location independent access by project managers and quick set-up of virtual enterprises reflecting both the short customer-supplier relationships in the industry and the need of construction firms to constantly re-configure and re-invent themselves. Method: Wonda will develop an open and secure framework for business objects and electronic payment. Business objects can be defined as software components, which encapsulate business rules and procedures and which can run anywhere on the network. They provide secure and sophisticated access to diverse electronic content and software applications. Indeed, just as a building can be described as a unique arrangement of standard products, a building project can be described as a unique arrangement of standard product data. Business Objects give a high level view of product data. They can be assembled into frameworks to support high-level views on industrial projects. The open framework will enable a distributed architecture through CORBA thus facilitating the interoperation of heterogeneous software components as found in legacy systems. The modular security of the framework and its support for electronic payment ensure authenication, confidentiality and non-repudiation as required for the business processes of construction virtual enterprises. Indeed the modular and incremental implemenation of security will be achieved partly through a Business Object architecture. Results will comprise o a pilot in 2 product cycles, o an open & secure framework architecture, o Commotion middleware for enabling business objects on top of Corba, o WeBuild (construction), WeBank (banking) and SILK (security) business objects o OpenDMX component to enable object orientated access to legacy databases.

summary	Overcoming barriers in the current building process that hinder the realisation of optimal energy efficiency in buildings is the aim of the Energy Impact Knowledge-based System [EIKS] project. During this project, a demo-version of a knowledge based assistive information and decision supportsystem was developed, considering the design and evaluation of integrated daylight and artificial lighting systems for office rooms. Twenty workshops with building experts were carried out in four European countries. The first set of sixteen workshops delivered the specifications of the system.During the second set of four workshops, this prototype was shown to some of the building experts who had attended one of the workshops of the first series. The outcomes of the first series EIKS workshops were very general and not really specifying the EIKS-prototype as expected. However, from the generally enthusiastic response of participants during the second workshop series it can be concluded that the prototype is a good basis for further development.

title	Anticipation in Evaluation and Assessment of Urban and Regional Plans
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	In order to start a move toward better computer based supporting tools for the assessment of urban and regional plans, a new research and development endeavour is proposed. In so doing, anticipation andanticipatory computing, i.e. a technique applying modelling and simulation, is found to be an interesting and promising point of departure. Hence, a fuzzy cellular automata computer model (STF) for simulation and anticipation of geographical or physical space is constructed. The main idea is to map anurban plan onto the STF for its assessing. STF has a normalised and continuous, i.e. fuzzy, system variable while both the time and space dimensions take on discrete values. Further, while ordinary cellularautomata use local rules, global ones are employed in STF, i.e. there is a total interdependence among all the cells of the automata. Outcomes of STF can be interpreted more as possible future states than exact predictions. Preliminary results seem to be well in line with main characteristics of planned urban or regional geographical spaces. Further, for the managing of multi-criteria choice situations, a fuzzy procedure – the Ordered Weighted Average (OWA) procedure – with continuous control over the degree of ANDOR-ness and with independent control over the degree of tradeoff, is proposed.

title	Built form and urban configuration development simulation
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The "centrality/potential" model, proposed by Krafta (1994), for configurational development, aims at the simulation of inner city built form growth. This is generally achieved by simulating the uneven distribution of floor area increments, resulting from replacement of old buildings, considered "devalued capital" form new ones. The model considers two main variables - public urban space system and built form - and treats them unevenly; the former is extensively disaggregated whereas the latter is not. This feature enables the model to make just a rough account of intra-urban built form development. The issue of built form simulation is then taken further in the following way: a) Urban built form is disaggregated by types. Buildings are classified by a cross combination of scale, purpose, age and quality standard; b) The city is itself considered as a set of intertwined typologic cities. This means that each unit of public space is identified by its dominant built form type, producing a multilayered-discontinuous city. Each one has its own market characteristics: rentability, technological availability and demand size; c) The market constraints determine which layer-city has priority over the others, as well as each one's size of growth. References to rentability and demand size gives each built form type priorities for development d) Spatial conditions, in the form of particular evaluation of centrality and spatial opportunity measures, regulates the distribution of built form increments and typological succession. Locational values, denoted by centrality and spatial opportunity measures, area differently accounted for in each layer-city simulation. e) Simulation is obtained by "running" the model recursively. Each built form type is simulated separately and in hyerarquical order, so that priority and replacement of built form types is acknowledged properly.

title	Tall Tensegrities - A Parametric Deformation Control Analysis
source	Odysseas Kontovourkis (ed.), Sustainable Computational Workflows [6th eCAADe Regional International Workshop Proceedings / ISBN 9789491207143], Department of Architecture, University of Cyprus, Nicosia, Cyprus, 24-25 May 2018, pp. 87-94
keywords	The design of tall structures with high slenderness, i.e. width/height ratio, and minimum self-weight, considers in addition to aspects of modularity, constructability and connectivity of the primary members, the static and dynamic behavior of the systems. Assuming constant mass and damping ratio over the height of the building, the structure necessitates respective definition of its stiffness properties, resulting from its configuration, i.e. geometrical stiffness, and the section properties of the members applied, for achieving controlled deformations under horizontal loading. In particular, structural deformation control is traced in the current paper in simplified means through a Finite-Element Analysis of a tall tensegrity structure with overall system dimensions of 12.12/96 m, i.e. 1/7.92 slenderness, developed in three different configurations. Furthermore, a differentiated pretension of the tension-only members of one of the systems has been applied for control of its response behavior. The parametric structural analysis of the tensegrity systems verifies the significant role of the tension-only elements in the system stabilization and horizontal response.

title	A FRAMEWORK FOR BUILDING DESIGN PROCESS MODELING WITH PARAMETER-BASED DESIGN STRUCTURE MATRICES
source	In C. J. Anumba (Ed.), Innovative Developments in Architecture, Engineering, and Construction. (pp. 25-31). Rotterdam: MillPress
summary	Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is utmost important. While the knowledge needed for building processes are distributed among the different participants from diverse disciplinary backgrounds, the product of their activities, i.e. the building itself, must be highly integrated. Despite the intense flow of information between design professionals, there is a lack of research to better understand and manipulate these flows. Furthermore, most of the current process modeling tools in the AEC industry do not enable analyses of iteration in the process and they represent the process at high levels with very little information at lower levels. In order to resolve the issues mentioned above, this paper introduces the use of parameter-based dependency structure matrix as a process modeling and system analysis tool for building design. The method reveals insights into the process structure, optimum sequence of parameter decisions, iterative cycles and concurrency in the process. A knowledge management framework for parameter-based DSM applications is proposed and the application of the framework is demonstrated through a real life building design problem.

title	A decision support system for housing of (public) organizations
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	In this paper we present a hierarchical decision support system for the allocation of organisations to available buildings, and for the allocation of employees of an organisation to the work units of a building. For both allocation problems a mathematical model and optimisation algorithm is developed, taking into account the relevant criteria, such as the extent to which the allocated floorspace is in accordance with the standards, and the extent to which departments are housed in connecting zones of a building. The decision support system is illustrated by two practical applications.

title	Information and communication technology (ICT) and intelligent cities: A Malaysian experience
source	In Mao-Lin, C. (Ed.), CAAD talk 4: Insights of digital cities (pp. 229-248), Taipei, Taiwan: Archidata
summary	This paper reports on Malaysian’s experience in suggesting and maintaining two cybercities (i.e. Putrajaya and Cyberjaya) or Intelligent Cities. The advantage of the convergence of technology has been implemented at national level as a means to increase human participation and to prosper in the Digital Age, in their daily life, business, education and other urban activities. It starts with an overview of ‘High-tech Corridors’ in Asia countries namely Philippines, Thailand, South Korea, and Singapore and its impact to these countries. The foundation of this study presents the criteria of Intelligent Community (IC) that makes a city intelligent without excluding the value of the citizen quality of life, culture and religion by associating with the Information and Communications Technology (ICT). We introduce and present www.i-Putra.com.my, a portal of digital soft city of Malaysia’s new administrative Capital, Putrajaya. This national project is funded by Putrajaya Holdings Sdn. Bhd. Malaysia and was originally developed by the Multimedia University before finally executed by I-Design Sdn. Bhd. It is designed to be an interactive channel to provide the services for different level of target audiences of the civic and urban activities. The guiding principle for i-Putra.com.my portal is content, context, community and commerce in which they will be integrated with the city information such as residential, commercial, service and public areas. It is hoped that this paper gives an example of good intelligent city concepts through a clear vision and planning, effective management, implementation and sustainable approach.

title	Effects with and of Computers and the Study of Computer-based Learning Environments
source	Chapter in Computer-Based Learning Environments and Problem Solving, ed. E. De Corte, M. C. Linn, H. Mandl, and L. Verschaffel. New York: Springer-Verlag
summary	Several factors have contributed to the developments in computer-based learning environments. Improvements and advances in hardware capabilities have afforded greater computing power. Advances in cognitive and instructional science have moved thinking beyond the limits of behavioural psychology. The new systems of computer-based learning environments are being designed with a view to facilitating complex problem-solving through integrating wholes of knowledge (Dijkstra, Krammer & Merriënboer, 1992). Thus, many see in the computer a means to enhance students' cognitive skills and general problem-solving ability. This is in spite of the fact that studies have failed to conclusively confirm the hypothesis that computer-based learning environments facilitate the acquisition and transfer of higher-order thinking and learning skills (Dijkstra, Krammer & Merriënboer, 1992). Salomon (1992) argues that computers make possible student involvement in higher-order thinking skills by performing many of the lower-level cognitive tasks, by providing memory support and by juggling interrelated variables. Through a partnership with the computer, the user may also benefit from the effect of cognitive residue resulting in improvement or mastery of a skill or strategy. Salomon explains: The intellectual partnership with computer tools creates a zone of proximal development whereby learners are capable of carrying out tasks they could not possible carry out without the help and support provided by the computer. This partnership can both offer guidance that might be internalized to become self-guidance and stimulate the development of yet underdeveloped skills, resulting in a higher level of skill mastery (p.252).

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Nowadays, most of building managers (e.g., companies, local communities, government agencies) have to face up a common set of problems. For instance, these problems are a deficient knowledge of ancient buildings and networks (e.g., gas, water), an inefficient management of green spaces, ora lack of communication between users (e.g., technical staff, suppliers, building end users). In addition, building and spaces to be managed may be shared among several distant areas. LAMIH works aim to achieve methodologies and computer tools for building management andassociated logistic. These works include two aspects we present in this paper:- a methodological one: the establishment of a project business plan, applied to building and logistic management,- a computer aspect: the design and implementation of a decision and management support system, the Geographical and Logistical Information System (G.L.I.S.). The project business plan includes the creation of a task force which has to lead the project and the description of the project plan.The G.L.I.S. is a software set which uses shared database. In particular, this set allows the different users to:- manage a patrimony as a whole, with the help of a Geographical Information System,- manage buildings and networks,- improve communication and logistic aspects with the help of a groupware tool. We present the achievement of these methodology and tools as part of a particular area: theUniversity of Valenciennes which is shared among four towns. The project takes into account existing buildings and those to be built, spaces which separates them, and the relationships betweenthe four different sites of the University. A task force is created as well as a specialised service, the Building Management Department. This department represents an interface between the task force,the LAMIH, and a centre of Information Technologies in construction (CERTIC) which is created as part of the SCENIC project (Support Centres Network for IT in Construction, Esprit project 21772).

title	Three-dimensional Input and Visualization
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 68-84
summary	The aim of this chapter is to investigate techniques by which man-computer interaction could be improved, specifically in the context of architectural applications of CAD. In this application the object being designed is often an assembly of defined components. Even if the building is not actually fabricated from such components, it is usually conceptualized in these terms. In a conventional graphics- based CAD system these components are usually represented by graphical icons which are displayed on the graphics screen and arranged by the user. The system described here consists of three- dimensional modelling elements which the user physically assembles to form his design. Unlike conventional architectural models which are static (i.e. cannot be changed by the users) and passive (i.e. cannot be read by a CAD system), this model is both 'user generated' and 'machine readable'. The user can create, edit and view the model by simple, natural modelling activities and without the need to learn complex operating commands often associated with CAD systems. In particular, the user can view the model, altering his viewpoint and focus of attention in a completely natural way. Conventional computer graphics within an associated CAD system are used to represent the detailed geometry which the different three-dimensional icons may represent. In addition, computer graphics are also used to present the output of the performance attributes of the objects being modelled. In the architectural application described in this chapter an energy- balance evaluation is displayed for a building designed using the modelling device. While this system is not intended to offer a completely free-form input facility it can be considered to be a specialist man-machine interface of particular relevance to architects or engineers.

title	CAD and Management of Construction Projects
source	Journal of Construction Engineering and Management, Vol. 112, December, pp. 557-565
summary	The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems have the potential to integrate construction data, although they appear to be almostignored. The use of 3-D modeling systems is considered to be the most suitable vehicle for successfully integrating these data. However, this is likely to necessitate the introduction of separate databases, preferably of the relational type. The use of 3-D modeling systems in assessing the construction implications of outline designs also presents interesting possibilities and is discussed.
